Legal claims defining the scope of protection, as filed with the USPTO.
5. The information obtaining apparatus according to claim 1 , wherein the fourth unit performs averaging processing on each of the pair of the image data pieces together with image data having a close imaging condition to the each of the pair of the image data pieces to generate two image data pieces and obtains the information about the blood vessel using the two image data pieces generated by performing the averaging processing.
6. The information obtaining apparatus according to claim 1 , wherein the first index value or the second index value is a pixel value when the first region or the second region is constituted of a single pixel and is an average value, a maximum value, or a minimum value of pixel values of a plurality of pixels when the first region or the second region is constituted of a plurality of pixels.
7. The information obtaining apparatus according to claim 1 , wherein the first region is at least a part of a region corresponding to an artery, a vein, or a new blood vessel group of a joint portion of a finger.
8. The information obtaining apparatus according to claim 1 , wherein the second region is set near the at least the part of the region corresponding to the artery, the vein, or the new blood vessel group set as the first region.
9. The information obtaining apparatus according to claim 1 , wherein each of the three or more image data pieces obtained by the first unit is image data of which a blood vessel part is subjected to position adjustment with each image data.
10. The information obtaining apparatus according to claim 1 , wherein each of the three or more image data pieces obtained by the first unit is image data generated by performing averaging processing on image data pieces having a close imaging condition.
11. The information obtaining apparatus according to claim 1 , wherein a different imaging condition includes a difference of a blood flow in an imaging portion.
12. The information obtaining apparatus according to claim 1 , wherein a different imaging condition includes a difference of a wavelength of light illuminating an imaging portion.
13. The information obtaining apparatus according to claim 1 , wherein the information about the blood vessel is generated as image data.
14. An image capturing apparatus comprising: a light source configured to illuminate a subject including a blood vessel with light; a detection unit configured to detect light emitted from the light source and propagating through the subject and generate an electrical signal; and an information obtaining apparatus configured to obtain information about the blood vessel using the signal from the detection unit, wherein the information obtaining apparatus is the information obtaining apparatus according to claim 1 .
15. The information obtaining apparatus according to claim 2 , wherein the fourth unit performs averaging processing on each of the pair of the image data pieces together with image data having a close imaging condition to the each of the pair of the image data pieces to generate two image data pieces and obtains the information about the blood vessel using the two image data pieces generated by performing the averaging processing.
16. The information obtaining apparatus according to claim 2 , wherein the first index value or the second index value is a pixel value when the first region or the second region is constituted of a single pixel and is an average value, a maximum value, or a minimum value of pixel values of a plurality of pixels when the first region or the second region is constituted of a plurality of pixels.
17. The information obtaining apparatus according to claim 2 , wherein the first region is at least a part of a region corresponding to an artery, a vein, or a new blood vessel group of a joint portion of a finger.
18. The information obtaining apparatus according to claim 2 , wherein the second region is set near the at least the part of the region corresponding to the artery, the vein, or the new blood vessel group set as the first region.
19. The information obtaining apparatus according to claim 2 , wherein each of the three or more image data pieces obtained by the first unit is image data of which a blood vessel part is subjected to position adjustment with each image data.
20. The information obtaining apparatus according to claim 2 , wherein each of the three or more image data pieces obtained by the first unit is image data generated by performing averaging processing on image data pieces having a close imaging condition.
21. The information obtaining apparatus according to claim 2 , wherein a different imaging condition includes a difference of a blood flow in an imaging portion.
22. The information obtaining apparatus according to claim 2 , wherein a different imaging condition includes a difference of a wavelength of light illuminating an imaging portion.
23. The information obtaining apparatus according to claim 2 , wherein the information about the blood vessel is generated as image data.
24. An image capturing apparatus comprising: a light source configured to illuminate a subject including a blood vessel with light; a detection unit configured to detect light emitted from the light source and propagating through the subject and generate an electrical signal; and an information obtaining apparatus configured to obtain information about the blood vessel using the signal from the detection unit, wherein the information obtaining apparatus is the information obtaining apparatus according to claim 2 .
